I just made my first project! (and my first topic) so I’d really love to have some input on some of the definitions I made up. I’d also like to know what other taxa commonly encounter IDable fragments on iNaturalist and if you think a project for fragments across more or for other taxa would be bene…

Defining fragment seems a little subjective, but I think saying anything less than 50% of the original shell makes sense. Probably don’t want to make it too complicated.

Cool project! I would assume limpets would follow the 50% rule too?

When I read [image] bonesigh: There should be minimal tissue left in the fragment I initially thought it meant there should be some tissue left in the fragment. Suggest to reword as “There should be little or no tissue left in the fragment”

Here are some common fragment species that need work (for my sake and if anyone wants to help) I’m sure there are a lot more around the world but these are the species I am familiar with from the southeastern US. I tried to sort of put them in order of how common they are found fragmented. Please a…

I’m always in favor of efforts to make a difficult category of ID more possible. Whether it’s shell fragments, plants out of season, leaf mines, or anything else – it’s projects like yours that create greater understanding and in the long term make these ‘tough’ IDs more practical and approachable.

Perhaps I should have called the topic “Fragment Project” because I truly would like to know if other taxa have fragments that are posted frequently. I am, however, very grateful for all the support everyone has given!!! I suppose it may just be that only seashells have any significant volume of f…

I agree, I think slipper snails and limpets would follow the 50% rule; the complete or undamaged whorl rule doesn’t make any sense for them. I will correct it, thanks!
